Hiring tips from our team
Advice for finding the right backend developer
Ask candidates to walk through a system they designed — how they handled scaling, failure modes, and trade-offs reveals real experience.
Prioritize candidates who write clean, testable code over those who optimize prematurely. Maintainability matters more than cleverness.
Give a take-home that mirrors your actual codebase challenges rather than algorithmic puzzles disconnected from real work.
Check for experience with your specific database and cloud provider. Switching between providers has a real ramp-up cost.
What companies say
Feedback from founders who hired through us
Keto Software
€1.7M ARR startup • Hired 4+ positions • Focus on European expansion hires
What we've delivered:
"Working with Herizon has been an absolute turning point for our hiring. They have already helped us successfully bring on board a Growth Marketing Manager and a RevOps Manager, and are now supporting us in finding the right AEs and a Partnership Development Manager. What sets Herizon apart is not only their deep understanding of every role in a revenue organization, but also their ability to truly grasp what we are looking for as if they were part of our own team. They don't just present candidates — they challenge our thinking, help us sort through priorities, and go deep with candidates to ensure we're meeting the right people. I couldn't recommend Herizon highly enough for any company looking to build out their revenue teams with the right people."
"Found people who actually understand the problem. They're from regions where sustainability challenges are real and motivation to solve them is high."
